Is all you are wanting is to know what the markings mean?
I am sorry, I cannot tell you who made this or where it was made, the markings do not show that. These are inventory markings, that show what the factory did to the item. Mahg, means it is Mahogany.
There is just no way to tell who made it by these nor where it was made.
At best all that can be done is valued this based on what it is.
You are welcome.
